Fine even if I don't find practically useful the constraint of "all users".
In effect without knowing the nature of the bug and the effective 
affected system, setting the severity to "grave" is a way to stop users 
from upgrading if they use apt-listbugs.
Probably the problem arise from the superposition of "priority" for 
developers and "severity" in the same tag.

Thanks, this solved the problem.

Could I suggest to add some notes in the changelog before closing the bug?

Thanks again.
